11.1 Information on toxicological effects Acute toxicity Harmful if swallowed, in contact with skin or if inhaled. Information available for the ingredients:

Oral LD50 Dermal LD50 Inhalation LC50 Ingredient

HYDROFLUORIC ACID -- -- 342 ppm/1 hour (mouse) Skin Causes severe burns. Contact may result in irritation, redness, pain, rash, dermatitis and severe burns. Eye Causes severe burns. Contact may result in irritation, lacrimation, pain, redness and corneal burns with possible permanent eye damage. Sensitisation Not classified as causing skin or respiratory sensitisation. Mutagenicity Not classified as a mutagen. Carcinogenicity Not classified as a carcinogen. Reproductive Not classified as a reproductive toxin. STOT - single Over exposure may result in irritation of the nose and throat, coughing and bronchitis. High level exposure exposure may result in intense thirst, ulceration, lung tissue damage, chemical pneumonitis and pulmonary oedema. STOT - repeated Not classified as causing organ damage from repeated exposure. Adverse effects are generally associated exposure with single exposure. Aspiration Not classified as causing aspiration.

12. ECOLOGICAL INFORMATION

12.1 Toxicity Accidental spillage of fluorosilicic acid may suddenly reduce pH levels in an aquatic environment. No visible toxic effects have been observed on biological components such as plants and algae, although fluorosilicic acid is moderately toxic to molluscs and fish. However, hazard for the aquatic environment is limited due to fluorosilicic acid having low chronic properties. The acid is highly dependent on environmental conditions: pH, temperature, oxidoreductive potential, mineral and organic content of the medium.

Acute ecotoxicity: Fish: 96 hr LC50 (Salmo gairdneri): 51 mg/L, (as fluoride); Crustaceans: 48 hr EC50 (Daphnia magna): 97 mg/L, (as fluoride), in fresh water conditions; Crustaceans: 96 hr EC50 (Mysidopsis bahia): 10·5 mg/L, (as fluoride), in salt water conditions; Algae: 96 hr EC50 (Scenedesmus sp.): 43 mg/L, (as fluoride). Chronic ecotoxicity: Fish: 21 days LC50 (Salmo gairdneri): from 2·7 - 4·7 mg/L, (as fluoride); Crustaceans: 21 days NOEC (Daphnia magna): 3·7 mg/L, (as fluoride).

12.2 Persistence and degradability Abiotic: · Air – neutralisation by natural alkalinity; · Water/Soil – ionisation/neutralisation of inorganic and organic materials; · Water/Soil – complexation/precipitation of inorganic materials. Degradation product: aluminium/iron/calcium/phosphate complexes and /or precipitates, as a function of pH (fluorides). Biotic; Not applicable as fluorosilicic acid is an inorganic compound.

12.3 Bioaccumulative potential Fluorosilicic acid has potential for bioaccumulation as fluorides into vegetables.

12.4 Mobility in soil · Air – mobility in aerosol form; · Water – considerable solubility and mobility; · Soil/Sediments – adsorption on minerals soil constituents – the proton occurring in clay may assist with neutralisation; may dissolve carbonate based materials; some material may remain for transport down towards the water table – on reaching the ground water table, the remnants of the acid may continue to move, in the direction of the ground water flow; · Conditions: slightly acid pH (fluorides) - lime addition may be required to rectify low pH resulting from fluorosilicic acid spillages.

SDS Date: 20 Aug 2019 ofPage5 7 CSBP-IF-11-037-07 Version 2.0 PRODUCT NAME FLUOROSILICIC ACID (22% SOLUTION)

12.5 Other adverse effects Avoid contamination of drains and waterways.

13. DISPOSAL CONSIDERATIONS

13.1 Waste treatment methods Waste disposal For small amounts (as determined by risk assessment or similar): Wearing the protective equipment detailed above, neutralise to pH 6-8 by SLOW addition to a saturated sodium bicarbonate solution or similar basic solution. Dilute with excess water and flush to drain. Waste disposal should only be undertaken in a well ventilated area. For larger amounts: Dispose in accordance with local regulations. Legislation Dispose of in accordance with relevant local legislation.
